- 1. Introduction to Trigonometry 10th Grade Mathematics Presentation
- 2. What is Trigonometry? • Trigonometry is the study of relationships between the angles and sides of a triangle, especially a right-angled triangle.
- 3. Sides of a Right-Angled Triangle • 1. Hypotenuse: The longest side • 2. Adjacent: Side next to the angle • 3. Opposite: Side opposite the angle
- 4. Basic Trigonometric Ratios • 1. Sine (sin) = Opposite / Hypotenuse • 2. Cosine (cos) = Adjacent / Hypotenuse • 3. Tangent (tan) = Opposite / Adjacent
- 5. Example: Using Sine Function • Given: Angle = 30°, Hypotenuse = 10 units • Find: Opposite side • sin(30) = Opposite / Hypotenuse • 0.5 = Opposite / 10 • Opposite = 5 units
- 6. Conclusion • Trigonometry helps in solving triangles using angles and side lengths. • Understanding basic ratios like sine, cosine, and tangent makes it easier to work with right- angled triangles.
